Two fixes for the 3M+ unhandled_promise_rejection events/day spike: 1. Filter: suppress "Error fetching ... 404" rejections from composition code — these are asset-not-found content errors, not Studio bugs. 2. Rate-limit: cap both error and rejection telemetry at 50 per session. After the cap, emit a single *_cap_reached event so we know capping occurred without generating unlimited events. 3. Root cause: webAudioTransport now checks response.ok before decode and caches failed URLs in _failedSrcs so repeat ticks don't re-fetch the same 404 on every playback frame. Also add playground/ to fallow ignorePatterns — local experiment directory was tripping the audit gate.
